My invention relates to trussed' structures, which may be used as walls,but which are particularly adapted for use as ioors and/0r roofs inresidential, office, commercial, and industrial buildings and the like.

More particularly my invention relates to 'cellular trussed structurespreferably made of formed sheet or strip, metal, preferably steel.

Most floor structures include joist members spanning between and beingsupported at their ends on bearing members which may be bearing walls ormay be beams or girders which in turn are supported at their ends uponother beams or girders or upon columns or bearing walls. c

The joint members are laterally spaced from each other, and support upontheir upper chords or flanges some form of oor- 0 ing or roofing, andmay carry below their lower chords or lianges some form of ceiling.

Many dilferent types of metal joists have been proposed for use in iioorstructures, and the flooring used for such joists is usually some formof concrete slab usually laid upon metal lath supported by the joists,or may be wood flooring secured directly to the joists.

In any event, steel j oists are relatively diiicult to fabricate forvariable spans and variable loadings, and the placement of steel joistswith the accompanying flooringv in a building is relatively diiicult andusually requires specially skilled labor for any particular type ofjoi'st floor structure,

Moreover, the complete l'loor including the joists and the ooring andthe ceiling, requires the assemblage of" materials usually 40 from twodiiferent sources, since the manufacturers of joists rarely supply thenecessary materials forthe liooringsand the ceiling.

The objects of the present improvements 5 -include in general theprovision of a cellular trussed structure including interlitting chordand web members, .for use primarily in buildings, and which may extendbetween and be supported by frame members of the building, and which mayform preferably a o load sustaining partition between the frame members,such partition, when extending verincludes a plurality of interlockingand in- ,terlitting members, all of which are preferably made of sheetor strip material, preferably of steel, and which result in a completedfloor structure having liooring above, ceiling below, and intertting andinterlocking joist 55 members between the Iflooring and ceiling members,whereby the improved Hoor structure may be placed in a building by theuse of relatively unskilled labor, and such door structures beingadapted for variable spans and for variable loadings withoutnecessitating excessive'y engineering and design cost.

Further objects of the present improvements include the pro-vision of atrussed cellular structure adapted for use as a lioor structure andincluding intertting members, .the several members being adapted foreasy and economical manufacture, and being adapted for easy andeconomical erection in the banding. f 8

Further objects of the invention include ,the provision of a. floorstructure enabling the elimination of the use of concrete in many typesof buildings.

83 These and other objects are attained by the present invention,thenovel features of which are particularly set forth in the appendedclaims. r f

Preferred embodiments of my invention -of my invention; and

are illustrated in the accompanying drawings forming part thereof, inwh1ch t Figure 1 is a fragmentary top plan view of a floor structureembodying the present improvements; 4

Similar numerals refer to similar parts throughout the several views.

ma be load7 re- While the present improvements used in the walls o fbuildings, the sisting truss action of the improvements 1s best attainedin floors, and accordinglyone floor structure embodying the present im-Erovements is indicated generally at 10 1n igs. 1, 2, and'3, andpreferably includes a.

plurality of panels each indicated generally at 11, and each Apanelincludes a plurality of side by side longitudinally4 and laterallyextending chord wall members 12, longitudinally and transverselyextending web wall members 13, and longitudinally extending angled panelside mem ers 14a and 146.

Some of the chord wall members 12 are l0- cated infan upper plane anddetermine a floor wall, and some of the chordwall members 12 are locatedin a lower plane and determine a ceiling wall, and the web wall members13 extend angularly between the spaced chord wall members 12 and formwith the s aced chord wall members 12, a plurality of side by sidelongitudinally. extending triangular cells 15.

The chord wall members 12 are preferably made of formed sheet or stripmaterial, whereby the floor wall is continuous across each panel, andlikewise the ceiling wall is `continuous across each panel, and incertain classes of buildings such as industrial buildings, require nofurther covering. When desired however, a relatively7 shallow lay ofInaterial, such as asphalt, linoleum, fibreboard, or the like, may beused to surface the floor wall, and/or ceiling wall.

The web wall members 13 may be made of formed sheet or stripmetal, asillustrated, or may be built up trussed joist structures when desired. l

Each chord wall member 12 includes preferably at each side alongitudinally extending fla-nge 16; and the flanges 16 are angular tothe web 17 of the chordwall member 12, and extending from one facethereof and towards each other, and each flange forming with the web ahook.

The flanges 16 of the upper chord wall members 12 extend downwardly, andthe flange 16 and the web 17 of a lower chord wall member 12 to a hookengagement at the opposite side with a flange 16and a web 17 of an-upperchord wall member 12; and each web wall member 13 preferablyincludes a web 19 and a longitudinally extending yflange 20a at one sidethereof, and a longitudinally extending flange 206 at the other sidethereof,

4the flanges 20a and 206 being angular to the web 19, and extending awayfrom opposite faces thereof, and form with the web an elongated Z asillustrated. The heads of the Zs` are formed by the flanges 20a and 206and the web, and the heads are interlockingly engged by the hook flanges16 of the members It has been found that this fundamental arrangement ofthe interfitting and interlocking members is not only practicallyself-sustaining, but is also adapted for carrying a relatively largesuperimposed load when the triangular cellular members are properlysupported at their ends.

' For increasing the rigidity and carrying capacity of the panel, theside members 14a and 146 are provided; and the side member 14a includesa lower ceiling web 21a having a longitudinally extending hook flange22a at one side, and having a beam'web 23a at the other side thereof,and the outer side of the beam web is provided with a longitudinallyextending abutment flange 24a.

Similarly the side member 146 includes a lower ceiling web 216 having alongitudinally extending flange 226 at one side, and having a beam web236 at the other side thereof, and the outer side of the beam web isprovided with a longitudinally extending abutment flange 246.

The side members 14a and 146 are provided for making a longitudinallyextending rectangular panel.

Laterally extending end members 25 are preferably provided for eachpanel`11, and each end member 25 has a laterally extending recess 26formed therein into which the ends of the longitudinally extendingmembers are fitted.

Each panel also preferably includes a plurality of laterally spacedtension members 27 arranged for applying a compression load on thelongitudinally extending members, and as illustrated each tension member27 is preferably in the form of a tie rod threaded at each end andextending through apertures in the end members 25, and each threaded endof each tie rod being provided with a nut 28 each nut abutting againstthe outer face of an end member, and, bein screwed against i the endmember for app ying the desired ing through apertures in the members 13and the beam webs 23a and 235 of the side members 14a and 146, and eachthreaded end of the tie rod is provided with a nut 31, each nut abuttingand being screwed against the outer face of one of the panel sidemembers.

A plurality of the panels may be utilized for making a floor of anydesired area as illustrated in Figs. 1, 2, and 3, by the use of upperlongitudinally extending filler members 32 and lower longitudinallyextending filler members 33 positioned between the sides ofadjacentpanels', and by the use of laterally extending ller members 34positioned between the ends of adjacent panels.

lt will be seen that the interlocking and i? 'eriltting members areself-sustaining and easily fitted together, so that the cellularstructure may be assembled on the ground or in position in a buildingstructure.

F ig. d illustrates another iloor structure including a modifiedembodiment of the improvements, indicated generally at 110.

The structure 110 includes -a plurality of panels each indicated at 111and each including a plurality of side by side longitudinally extendingtriangular tubular' members 112, each preferablyformed from sheet orstrip metal and including a wall web 113 from the sides of which beamwebs 114e and 114?) extend away from one face of the Wall web andtowards each other and the outer sides of the beam webs are preferablyprovided, respectively, with longitudinally extending flanges 115e and115 parallel with the wall web.

A plurality of wall members 116, each include at each side thereof alongitudinally extending snap flange 117 and the snap flanges of thewall members 116 make snap engagement between the apexes 118a and 1186,respectively; the apexes 118e and 1186 being formed by the outer sidesof the beam webs 114e and 114?) and the flanges 115e and 1155.

Fig. illustrates another floor structure 210 including a furthermodified embodiment of the present improvements, and the structure 210is similar to the structure 10,

means being provided for bolting the longitudinally extending members toeach other and for applying screed strips.

The structures 110 and 210 will be set forth in greater detail and thenovel features thereof claimed in other applications for patent.
